Got back from a 2000 mile roundtrip with some track time and car is still holding up great. Have over 40k on the odometer with close to 60 track days and she's doing great. Just had the front control arms replaced under warranty, thanks BMW/IND and she rocks

That's a good amount of miles, and a huge amount of track days! Glad the car is holding up well. What tipped you off to needing new front control arms?
